# PaddleHub实现口罩佩戴检测应用
# 基于PaddleHub实现口罩佩戴检测应用
## 0 项目介绍
本文档基于飞桨本次开源的口罩佩戴识别模型, 提供了一个完整的支持视频流的WebDemo，以及高性能的Python和C++集成部署方案, 可用于不同场景下的软件集成。
## 目录
- [1. 搭建视频流场景的WebDemo](#1搭建视频流场景WebDemo)
- [2. 高性能Python部署方案](#2高性能Python部署方案)
- [3. 高性能C++部署方案](#3高性能c部署方案)
## 1. 搭建视频流场景WebDemo

##### 背景
本项目可以部署在大型场馆出入口，学校，医院，交通通道出入口，人脸识别闸机，机器人上，支持的方案有：安卓方案（如RK3399的人脸识别机，机器人），ubuntu 边缘计算，windowsPC+摄像头，识别率80%~90%，如果立项使用场景可以达到 99% （如：人脸识别机场景）。但是限于清晰度和遮挡关系，对应用场景有一些要求。

##### 效果分析
可以看到识别率在80~90%之前，稍小的人脸有误识别的情况，有些挡住嘴的场景也被误识别成了戴口罩，一个人带着口罩，鼻子漏出来识别成没有戴口罩，这个是合理的因为的鼻子漏出来是佩戴不规范。初步判断，这个模型应用在门口，狭长通道，人脸识别机所在位置都是可以的。
